NEW QUESTION # 71
Typically, which top level system directory is used for files and data that change regularly while the system is running and are to be kept between reboots? (Specify only the top level directory)
- A. Var
- B. /var/,
- C. var/
- D. /var
Answer: D
Explanation:
Explanation
The top-level system directory that is used for files and data that change regularly while the system is running and are to be kept between reboots is /var. The /var directory contains variable data that changes in size as the system runs. For instance, log files, mail directories, databases, and printing spools are stored in /var. These files and data are not temporary and need to be preserved across system reboots. The /var directory is one of the few directories that are recommended to be on a separate partition, according to the Filesystem Hierarchy Standard (FHS)1. This is because the /var directory can grow unpredictably and fill up the / partition, which can cause system instability or failure. By having /var on a separate partition, we can limit the amount of disk space that can be used by variable data and prevent users from affecting the / partition. The /var directory is also a common target for malicious attacks, so having it on a separate partition can improve the security and isolation of the system. References:

NEW QUESTION # 73
Which permissions and ownership should the file /etc/passwd have?
- A. -rw-------1 rootroot531 Jun 5 22:45 /etc/passwd
- B. -rw-r--r--1 rootroot531 Jun 5 22:45 /etc/passwd
- C. -rw-r--r--1 11531 Jun 5 22:45 /etc/passwd
- D. -rw-------1 11531 Jun 5 22:45 /etc/passwd
Answer: B
Explanation:
Explanation
The correct permissions and ownership for the file /etc/passwd are:
B: -rw-r-r-- 1 root root 531 Jun 5 22:45 /etc/passwd
The /etc/passwd file is a plain text-based database that contains information for all user accounts on the system. It is owned by root and has 644 permissions. The file can only be modified by root or users with sudo privileges and readable by all system users. The permissions and ownership of the file are important for the security and functionality of the system. The permissions and ownership of the file can be viewed by using the ls -l command. For example:
ls -l /etc/passwd
The output of the command will show the following information:
-rw-r-r-- 1 root root 531 Jun 5 22:45 /etc/passwd
The first column shows the permissions of the file, which are composed of 10 characters. The first character indicates the file type, which is - for regular files. The next nine characters indicate the permissions for the user (owner), the group, and the others, respectively. Each set of three characters indicates the read , write (w), and execute (x) permissions. A dash (-) means no permission. In this case, the permissions are:
* rw- for the user, which means the user can read and write the file, but not execute it.
* r-- for the group, which means the group can only read the file, but not write or execute it.
* r-- for the others, which means the others can only read the file, but not write or execute it.
The second and third columns show the owner and the group of the file, which are both root. The root user is the superuser or the administrator of the system, who has full access and control over the system. The root group is the primary group of the root user, which usually has no other members.
The fourth column shows the size of the file in bytes, which is 531 in this case. The fifth and sixth columns show the date and time of the last modification of the file, which are Jun 5 22:45 in this case. The last column shows the name of the file, which is /etc/passwd in this case.
The other options are not correct because:
* A: -rw------- 1 root root 531 Jun 5 22:45 /etc/passwd: This option has the wrong permissions for the file.
The permissions are 600, which means only the user (root) can read and write the file, and the group and the others have no permissions at all. This would prevent the system users from reading the file, which would cause problems for the login process and other utilities that rely on the file.
* C: -rw-r-r-- 1 1 531 Jun 5 22:45 /etc/passwd: This option has the wrong owner and group for the file.
The owner and group are both 1, which is the numeric ID of the user and group. However, the numeric ID of the root user and group is 0, not 1. The user and group with the numeric ID of 1 are usually bin, which is a system user and group that own some system binaries and directories. Thebin user and group should not own the /etc/passwd file, as this would compromise the security and functionality of the system.
* D: -rw------- 1 1 531 Jun 5 22:45 /etc/passwd: This option has both the wrong permissions and the wrong owner and group for the file. The permissions are 600, which means only the user can read and write the file, and the owner and group are both 1, which is the numeric ID of the bin user and group.
This would prevent the system users from reading the file, and give the bin user and group full access to the file, which would cause problems for the security and functionality of the system.

- B. Hard links are specific to one filesystem and cannot point to files on another filesystem
- C. If users other than root should be able to create hard links, sulnhas to be installed and configured
- D. Hard links are not available on all Linux systems because traditional filesystems, such as ext4, do not support them
- E. Each hard link has individual ownership, permissions and ACLs which can lead to unintended disclosure of file content
Answer: B
NEW QUESTION # 76

NEW QUESTION # 77
Which of the following commands determines the type of a file by using a definition database file which contains information about all common file types?
- A. file
- B. type
- C. hash
- D. pmagic
- E. magic
Answer: A
Explanation:
Explanation
The file command determines the type of a file by using a definition database file which contains information about all common file types. The database file is usually located at /usr/share/misc/magic or /usr/share/file/magic and can be customized by the user. The file command analyzes the content and structure of the file and compares it with the patterns in the database file to identify the file type. The file command can also check the file name extension, but it does not rely on it. The other options are either invalid or do not perform the desired task.The magic, pmagic and hash commands are not valid Linux commands. The type command is used to display information about command type, not file type.

NEW QUESTION # 81
Which of the following commands kills the process with the PID 123 but allows the process to "clean up" before exiting?
- A. kill -TERM 123
- B. kill -PIPE 123
- C. kill -STOP 123
- D. kill -KILL 123
Answer: A
Explanation:
Explanation
The command kill -TERM 123 kills the process with the PID 123 but allows the process to "clean up" before exiting. The option -TERM specifies the signal to be sent to the process, which is the termination signal (SIGTERM). This signal requests the process to terminate gracefully, which means that the process can perform any necessary actions before exiting, such as closing files, releasing resources, or saving data. The process can also catch the signal and ignore it or handle it in a different way, if it is programmed to do so. The syntax is: kill -TERM pid. For example, kill -TERM 123 will send the SIGTERM signal to the process with the PID 123, asking it to terminate nicely. The other options are not correct because:
* A. kill -PIPE 123: This command sends the broken pipe signal (SIGPIPE) to the process, which is not used to kill the process, but to notify it that the other end of a pipe has been closed. This signal is usually ignored by the process, unless it is writing to the pipe, in which case it will cause the process to terminate1.
* B. kill -KILL 123: This command sends the kill signal (SIGKILL) to the process, which is the most powerful way to kill the process, but it does not allow the process to "clean up" before exiting. The SIGKILL signal cannot be caught, blocked, or ignored by the process, and it forces the process to terminate immediately, without performing any actions. This command should be used as a last resort, when the process is unresponsive or causing harm to the system2.
* C. kill -STOP 123: This command sends the stop signal (SIGSTOP) to the process, which is not used to kill the process, but to pause it. The SIGSTOP signal cannot be caught, blocked, or ignored by the process, and it suspends the execution of the process until it receives a continue signal (SIGCONT). This command can be used to temporarily stop a process from running, without terminating it3. References:

NEW QUESTION # 82
When in Normal mode invi, which character can be used to begin a reverse search of the text?
- A. r
- B. /
- C. F
- D. ?
Answer: D
Explanation:
In vi, the ? character can be used to begin a reverse search of the text. This means that the search will start from the current cursor position and move backwards towards the beginning of the file. The search pattern can be any regular expression that matches the desired text. To repeat the search, the user can press n for the previous match or N for the next match. The / character can be used to begin a forward search of the text, which means that the search will start from the current cursor position and move forwards towards the end of the file. The F and r characters are not used for searching, but for other commands in vi. The F command is used to move the cursor to a previous occurrence of a specified character in the current line. The r command is used to replace the character under the cursor with another character. References:
